SELF UNLOADING LOG BARGE Filed June 21. 1928 Patented Jan. 6, [17931 t Unirse STATES PAU-:Nr orsiei--1` f GEORGE sALATHIEI. WILBAND AND JOHN THADDAUS WILBAND, or vnivconvnn, e Bm'risn COLUMBIA, cANAnA e A sELr-UnLoAniNe Los Benen Application inea June 21, was, serial No.

The invention relates 'to improvements-in self unloading log barges, as described in the present kspecification andvillustrated inthe drawings that form part'of thesame.

,5j `The invention consists essentiallyv of the novel arrangement and construction of parts, wherein a barge having a specially-constructed keelson' extending above the deck thereof is .adapted to have extending towers therefrom, said towers having mounted at the top thereof a suitable shaft extending longitudinally the length of the barge; the said barge is provided with a plurality of hinged stanchion-s along each side, each of said stanchions having a guy wire secured thereto andy removably connected to aforesaid shaft, the said stanehions through suitable chains removablyV secured yat the bottom thereof adapted toy permit of same acting as binding element in normal operation. The decky yof 'the barge 'has suitable tapering declined skids extending from the'aforementioned keelson on either side thereof. f

`The objects 4of the invention are to 'devise a log barge, the construction and posi-A t'ioning ofthe elements thereof adapted to permit of ease rand quickness in' loading, tightlyfbinding the load in transit, and to permit of quickness in self unloading from alternate sides. A further feature is the constructionv of a rigid and strong barge. Referring to the drawings:`

l represents a barge ofany suitable lines,l having a 'centerleelson 2' extending abo-ve the declrB as at 4 'g' the said k-eelson'has secured thereto and extending upwardly therefrom and spaced apart a plurality of any desired number of towers, the said. towers adapted to have mounted at the top a shaft 6,". said shaft extending centrally the length of said barge and having suitable connections at the: bow thereof to some prime mover, adapted to cause the said shaftto revolve, the purpose of which will later be explained,

Secured to the deck in spaced pairs area plurality of tapered declined skids? extending from the keelson 2 ltoward either side of the barge. Between the said skids are hingedly secured stanohions 8 by means of a special' hingecomprising amobile portion 9 secured to the outside of the stanchion and' provided with` two oppositely disposed lugs 10, the stationary porti-on.A 11 secured to the deck and provided with an eye y12. Y

The stanchions 8 are'held in normal up! right position by means of a pair of chains 13, secured at one end in the: eye. 12, the opposite ends engaging the aforesaid lugs l() of the mobile portion 9. f

A guy wire VliA is provided one toeach 111tstanchion adapted togextend and be removably connected to'the aforementioned sha-ft' 6 by means of an eye of suitable design en-- gaging a'liook 15,'saidhoolr`l5 positioned on the `vshaftene opposite to4 each stanchion, @5*

ing., consequently we have devised our barge im'.

(ill.

tightening vof said chains Ybringing the stanchions into binding engagement whereby ther loadis tightly and rigidlyfheld in position,- the said load being divided by means of the VVextending portion Il of the keelson. HavinO loaded the barge, theY guy wires 14 on either side aresecured to the shaft and the said shaft revolved` suiiciently to `tighten same, the said tightening of ythe wires mak-v ing a further binding of the stanchions Having transported the barge full of logs to itsdestination', the operation of unloading is as follows: the chains 13 are disengaged from the lugs 10 on both sidesY of the barge, and theshaft revolved in contrawise manner uns til the tension on oneside has been released to free the eyes of the wires from the shaft hooks, whereupon the stanchions on that side will lfall outwardly and downwardly into the water then acting as buffers to protectthe sides of thebarges from the released and kfalling logs, and it will readily be seen that the logs when released, will be Yassisted in their unloading vby the tapered declined skids, lthe further revolving oftheA shaft in the same direction will release the wires on the other side in like manner aforementioned, the barge having listed to the ,oppositey side due tothe lightening ofthe load through the first release of the logs, and itwillbe seen that by the releasing in alternate operations Y' will cause an oscillatory listing until theentire load is disposed of, whereupon the barge willV assume the position as shown4 in Figure 8, but with the stanchionsv and wires in the water at the side of the barge, and to aid in bringing thev said stanchions Afrom this position to'vtheirfnormal upright position'jwe provide aA boom arinV 2O pivotally secured between the skids, havingsuitable tackle op'- erating thereon, Vwhereby the said stanchions may be raised. i

, t will be seenlthat weliave devised a bargev having a center keelson adapted to strengthen they barge and divide the load,

suitable means connected to a rotatable shaft adapted to .allow of quick unloadingv of the barge, thereby reducing the time and labor in unloading to a minimum. Y

We claim 1. In self unloading log barges,'in combination,-a barge having a center keelson adaptedV to extend above the deck thereof, a

' plurality of shaft supporting towers, secured y that the'log g lying next to said stanchions will cause the to and extending above the said keelson and spaced one from the other, adapted to have mounted thereonY a rotatable shaft, said shaft having suitable hooks secured thereon and spaced one from the other, a plurality of tapered declining skids, extending from the keelson toward either side of the barge, arranged in spaced pairs, a pluralityA of hinged stanchions positioned within said skids',KV the mobile' portion' of theLV hinge havingoppositelyV disposed lugs formed thereon, and the vrstationary portion of the hinge being provided with an eye, a pair of chains, secured'to said'eye of eachstationary hinge, and removably secured to the lugs of the mobileportion of the hinge-inyan angular manner, cables secured at one end to stanchions and ,engaging through suitable eyesV the hooks on the shaft, said cables upon rotation of aforesaid shaft adapted to be tightened and bindv the aforesaid stanchions toY the load. Y

r2. In self unloading log barges, 1n combination',- a barge having a center keelson,

adapted to extend above the'` deck thereof,

a .plurality of shaft supporting towers secured to and extending above the said keelson and spaced one from the other, adapted to have mounted thereon a rotatable shaft, said' shaft having suitable hooks secured thereon and spaced one from theother, a plurality of tapered declining skids extending .from the keelson toward either side of the'barge arranged in spaced pairs, a plurality of hinged stanchions positioned within the Ypairs of "i skids, the-'mobile hinge portion having' op-` positely disposed lugs formed thereon and the stationary hinge portion having an eye formed thereon, a pair of chains secured to said eye of stationary hinge portion and removably secured to theA lugs of the mobile portion in angular manner, cables secured at one end to aforesaid stanchions, engaging through suitable eyes'the hooks on aforesaid shaft, all the cables on one side of the barge adapted upon rotation of shaft to be released,V and upon further reverse rotationy of shaft to release all cables on vopposite side. saidrelease of cables adapted to permit of aforementioned stanchions to fall to side of barge and act as buffers, and also causing a disturbent state of trim whereby a controlled sequence of oscillatory listing takes place,fa plurality of boom arms pivotally secured between aforesaid pair of skids adapted through suitable tackle to assist in raising stanchions to normal'upright position.

3. In selfsunloading log-barges, in combination, a barge having a center keelson adapted to extend above the deck thereof, a pluralityof shaft supporting towers secured to and extending above the said keelson in spaced apart relation and having mounted thereon a rotatable shaft, a-'pluralityof'den `clined transverse skids extendingfrom each n side of saidkeelson toy each side of the barge, Y

' ther rotation of the shaftin the same direction the cables connected with the stanchions' on the other side are similarly released and the said stanchions allowed to fall to the side of the barge and act as bulfers, and whereby the sequential release of the cables and stanchions first on one side and then on the` other results in an unstable condition of trim, thus setting up a controlled sequence of oscillatory listings thus permitting the load of logs to automatically and gradually unload into the water on each side.

4. In self-unloading log-barges, in combination, a barge having a centre keelsonl adapted to extend above-the deck thereof, a plurality of shaft supporting towers secured tofand extending above the said keelson in spaced apart relation and having mounted thereon a rotatable shaft, a plurality oit' declined transverse skids extending from each side of said keelson to each side of the barge, a plurality of hinged stanchions in spaced apart relation positionedalong the deck in alignment and adjacent each side of said barge, cables secured at one end to said stanchions and being at the other end in releasable engagement with said shaft whereby upon rotation of theshaft the cables in connection with the sta-nchions on one side of the barge are simultaneously released and upon further rotation of the shaft in the same direction the cables connected with the stanchions on the other side are similarly released and the said stanchions allowed to fall to the side of the barge and act as buffers,A and whereby the sequential release of the `cables' and stanchions first on one side and then on the other results in an unstable condition` of trim, thus setting up a controlled sequence of oscillatory list-ings thus per1nitting the load of logs to automatically and gradually unload into the water on each side, a pluralit.7 of boom arms projecting beyond the side of said barge and adapted through (suitable tackle to assist in raising the Vsaid f'stanchions to their normal upright position'.l GEORGE SALATHIEL WILBAND.
